Application filed February 3, 1913.

To all whom it may concern Be it known that we, GEORGE C. CARD and VVILLIAM MYERs, both citizens of the United States, residing at Seattle, in the county of King and State of WVashington, have invented a certain new and useful- Improvement in Vinches, of which the fol lowing is a specification.

Our invention relates to improvements in winches; and the object of our improvement is to provide a winch that shall be adapted easily to pull, haul, hoist or move, a body when but little power is applied to operate such winch for the required time; and which will be simple in its plan of construction and have great capability in proportion to its size and weight; and which, further, shall be so constructed that in its operation the two portions of a loop of a cable that may extend from it shall be disposed substantially in the same vertical plane whereby a man or animal readily may step over the two portions of its loop of cable or its two cables at the same time. We attain this object by devices illustrated in the accompanying drawings, wherein-- Figure 1 illustrates a winch embodying our invention by a view in side elevation wherein sorne of its parts are shown in vertical-section, Fig. 2 is a plan View of a portion of the same with certain parts removed which parts are shown in Fig. 1 as being disposed above broken line 00, a Fig. 3 is a perspective view of a fragment of a detail of the same, Fig. 1 is a like view of another part of the same, Fig. 5 is a plan View showing a form of two associated gearwheels embodied in our invention, Figs. 6 and 7 are perspective views of details, of our invention and Fig. 8 is a plan view showing associated parts of our invention and their relative positions. 7

Like reference numerals indicate like parts throughout the drawings.

Referring to the drawings, two shafts 9 and 10 respectively are disposed vertically to be rotatable within suitable bearings in a supporting frame comprising a bed-plate 11, a top-plate 12, a connecting brace 13 and brace-rods 14, 14.

Mounted rigidly on shaft 9 and extending between the upper-plate 12 and the bedplate 11 is a winding-drum 17 provided with a lower flange and an upper flange 16. The lower flange 15 is provided with a hole within which is disposed a hook 18 whose Specification of Letters Patent.

Serial No. 745,982.

sleeve 19 is secured to the end of that portion of a cable 20 which is wound around the lower portion of the winding-drum 17, which cable 20 leads from the windingdrum 17 to and through a pulley-block 21 which is secured by a strap 22, hook 23 and rope 2 1 to a stump 25, and from pulleyblock 21 the other end portion of cable 20 leads to and is wound upon another windingdrum that is mounted upon the shaft 10 and provided with an upper flange 26 and a lower flange 27.

The upper side of each of the flanges 16 and 26 is provided with a toothed ratchet 28 disposed in a circle concentric with its drum, such ratchet 28 being sunk in the surface of the flange, as more clearly indicated in Fig. 3, which shows perspectively a fragment of the wind ng-drum 17, the flange 16 and the upwardly projecting portion of the shaft 9 which are similar to corresponding parts of shaft 10.

Pivotally disposed in each of two oblong holes 29 and 30 are a pair of pawls 31, 31, the pawls 31, 31 in the holes 29 being adapted to engage with the ratchet 28 of the flange 16 while the pawls 31, 31 in the hole 30 may engage with ratchet 28 of the flange 26 and each pair of the pawls 31, 31 may be raised, if desired, and disengaged from its ratchet 28 by a string 32 that may be held by ones hand or tied to a convenient fixed object not shown, Fig. 6 shows by a perspective view the form of a paw. 31 whereon the projection 33 serves for connecting with said string 32, the slot 34 being adapted to receive a pivot (not shown) and the holes 35, 35 serve to receive a pin (not shown) that may confine such pivot within said slot 34 whereby the pawls 31, 31 may swing on such pivot.

The upwardly projecting portions of the shafts 9 and 10 are alike in form and dimensions, which fo m is more clearly illustrated in Fig. 3, wherein the shaft 9 in its uppermost squared portion 36 is provided on its opposite sides with slots 37, 37 of semi-circular cross-section while its cylindrical portion is provided with a vertical slot 38 as shown.

Upon the cylindrical portion of shaft 9 that projects above the top-plate 12, as shown in Fig. 1, there is disposed a gearwheel 39 and above it a gearwheel 40 which gearwheel 40 is adapted normally to rotate freely on and around said shaft 9 while said gearwheel 39 is prevented from turning on said shaft 9 by a feather 41 secured in the boring of said gearwheel 39 said feather 41 projecting within the vertical slot 38. Each of the gearwheels 39 and 40 is provided with holes 42, 42, 42, 42, said holes 42 in the gearwheel 39 being disposed to register with the corresponding holes 42 in the gearwheel 40 whereby said gearwheels 39 and 40 may be locked to revolve together by inserting plug 43 of the form shown in Fig. 4. Upon the cylindrical portion of the shaft 10 above said top-plate 12 is mounted normally to turn freely thereon a gearwheel 44 and above said gearwheel 44 is removably mounted a larger gearwheel which is prevented from turning on said shaft 10 by a feather 41 which engages with the slot 38. The larger gearwheel 45 and the smaller gearwheel 44 are each provided with holes 42 disposed like the holes 42 in gearwheels 39 and 40 whereby the plug 43 may look the gearwheels 44 and 45 together to be turned by the shaft 10. The pitch diameters of the small gearwheel 40 and the large gearwheel 45 and their relative positions are such as to cause their respective teeth properly to mesh during their rotation, while the larger gearwheel 39 and the smaller gearwheel 44 are likewise adapted to engage with each other in their rotation.

Upon the squared portion 36 of each of the shafts 9 and 10 is mounted a disk 46 provided with a hub 47 through which hub 47 extend holes 48 disposed to register with the semi-circular slots 37 disposed on opposite sides of the squared portion 36 within'which holes may be disposed key-pins 49, as shown in cross-section in Fig. 1, whereby the disk 46 may be securely fastened to the squared portion 36. The disks 46, 46 are similar in all respects so that a sweep 50 may be attached to either one or the other of said disks 46, 46 as may be desired, in the practical operation of the winch.

The sweep 50 may be attached to one of said disks 46 by means illustrated in Fig. 1 and in Fig. 8 wherein a flat plate 51 is riveted 'to the underside of the sweep 50 by rivets 52 and upon the under surface of said plate 51 are secured brackets 53 of a size, form and disposition to adapt them to engage with disk 46, in the manner shown in Fig. 1. EX- tending downwardly through the sweep 50 and through the plate 51 is a hole disposed to register with a hole 54 disposed in the top end of each of the squared portions 36 of the shafts 9 and 10, within which holes may be di iosed a king-pin 55.

As more clearly shown in Fig. 8, brackets 56 are disposed on each side of the sweep 50 within which are pivoted dogs 57 of a form illustrated in Fig. 7, whereby each may be disposed, as shown, to engage with the side of one of the four holes or recesses 58 dis posed at equidistant points near the outer edge of the upper side of the disk 46.

Each of the dogs 57 is articulated by means of a connecting rod 59 with the end of a lever 60 which is pivoted by pivot 61 to the top surface of the sweep 50 as shown, whereby when said lever 60 is disposed in a direction parallel with the lengthwise direction of the sweep 50, as shown in Fig. 8, then the two dogs 57 will be free from contact with the disk 46, but if the handle 62 of said lever 60 be moved sidewise toward the righthand, then the left-hand dog 57 will be lowered to fall into one of the recesses 58 while the right-hand dog 57 will be raised higher from the disk 46 in an obvious manner; and manifestly if the handle 62 be moved toward the left-hand a directly contrary effect upon the dogs 57 would result. Thus the sweep 50 by its associated devices described may be operated to turn in either direction, as required, or it may be caused to remain stationary while the shaft to which it is attached is turning in response to a movement of the cable 20.

Upon the inner sideof the stud 13 we have provided a saddle 63 that is slidably adjustable vertically by means of adjusting screws 64 said saddle 63 being adapted to serve as a seat within which to dispose a rope sling 65 whereby the winch may be secured in a fixed position by fastening said sling 65 to some fixed object, as to a stump 66, and when the winch is so fastened to a fixed object the saddle 63 may be adjusted vertically by adjusting screws 64 to a de sired point on stud 13.

Manifestly a winch embodying our invention as described, is adapted to be operated to move light objects at a high rate of speed or to move very heavy bodies at a low rate of speed, for instance, a single cable might be connected on the drum of the shaft 10 with an end attached to a light object to be moved, then if the plug 43 be inserted through holes 42 of gearwheels 44 and 45 to lock them together a rotation of the shaft 9 by a movement of the sweep 50 would communicate motion to the larger gearwheel 39 and the smaller gearwheel 44 to cause the shaft 10 with its drum to rotate at twice the speed of shaft 9, said larger gearwheel 39 being twice the size of said smaller gearwheel 44. Or, a single cable might be attached. to the drum 17 of shaft 9 and to an object to be moved, and the plug 43 removed from the winch, in which case said drum 17 would be turned independently of the drum. of shaft 10 and at the same speed as that of the movement of the sweep 50. Or, the sweep 50 might be transferred to the shaft 10 with the plug 43 disposed to lock gear-wheels 44 and 45 together, then a movement of the sweep 50 would cause the drum 17 to rotate at half the rate of speed of shaft 10 since the smaller gearwheel 44 would then be the driving gearwheel and would act to engage with the larger gearwheel 39. Or, as shown in Fig. 1, a pulley-block 22 disposed within the loop of a cable might be attached to an object, as a stump 25, and one end of such cable be connected to the drum 17 while its other end is connected to the drum of shaft 10 and wound thereon in the same direction, the sweep 50 being attached to shaft 9 and the plug 43 disposed to lock gearwheels 39 and 40 together whereupon if the sweep 50 be turned the shaft 9 would revolve twice as fast as the shaft 10 by reason of the relative sizes of the driving and driven gearwheels, but in a different direction of rotation to cause the cable 20 to be wound upon the drum 17 at a greater rate of speed than it would be unwoundfrom the other drum, thus to move slowly to shorten the loop of the cable 20 to move with great power the object acted upon.

Under some conditions of operation the gearwheels 39 and 4st might be dispensed with in which case the gearwheel 40 would have to be fastened upon the shaft 9 in a fixed circumferential position.

Other obvious changes with relation to the different positions of the several parts of the winch may be made to serve different requirements.

Of course the form and size of parts of the structure may be varied and any minor modifications may be made in the winch described without departing from the spirit of our invention.
